Yes, you need personality, good communication skills and good attitude. So, I don't think maths as an optional subject in class 12 will create any problem.

Yes, you can and it is not necessary that your Bachelor's degree should be related to the aviation field. Even after 12th, you can apply for pilot training. For the career as a pilot and the ways to become a pilot, you may refer to the link below:

Dear Jyoti,
To study Aeronautical Engineering, you need to have the below requirements to be eligible for the course. To be an aeronautical engineer one should have a graduate degree (B.E/B.Tech) or at least a Diploma in Aeronautics. The basic eligibility criteria for a BE / B.Tech is 10+2 or equivalent examination, with Physics, Chemistry and Mathematics and must have a fairly high percentage of marks in the aggregate.

Yes, of course, you can take admission without having maths as a subject in class 12th.

Hello Vaishnavi!

Hello Anubha, You can't become a pilot by using this degree, only you become an Engineer in that particular field. To become a pilot, you need to do SPL and CPL courses separately, for that you need to have +2 with physics, maths, with 50% marks.
